Taking the aerial off the car is not a difficult job and this article will explain how to do it and what tools you will need in as much detail as possible.

Antenna Base Removal

Here is a diagram showing the parts of a genuine Ford Focus aerial.
Some of the above parts sit on top of the roof and some are accessible
from inside the vehicle.

Step 1. unscrew the aerial mast from the base.If you grip the aerial where the arrow is shown and rotate it anti-clockwise,it should unscrew from the base. This should then just leave you with the
aerial base like this ;

Step 2. Removing the interior light.

In order to remove the rest of the aerial, you will need to access the rear of the interior light.

The front cover can be easily be taken down by firstly unclipping the edge nearest tothe windscreen. Inserting a screwdriver or any blunt object (I have heard of people using a coin) between the clear lense and plastic frame. Once the front edge is unclipped, the same can be done with the rear.

Step 3. Disconnecting the interior light.

When you have completed step 2 and allowed the lense to drop down, you will see that ithas wires conected to it, se below ;

These wires just connect via ‘push-in’ or ‘spade’ type connectors. Just pull them apart.

Don’t worry about where to refit them later, as the spades are different sizes and can onlygo back in the correct positions.

Step 4. Removing the interior light plastic surround.

The plastic surround (or bezel) of the interior light needs to be removed.

It is held in place on each side and these screws need to be removed and the
surround can then be removed.

Step 5. Removing the aerial cable and base.

The aerial cable and aerial base (on roof) are held in place by a ‘Torx head screw’, T20 size we believe.

In order to remove these Torx screws, you will need a suitably sized Torx bit.
These are inexpensive, and can be purchased at most auto-shops or online. Here is a link to where you can buy Torx sets cheaply online. It is probably best to buy a cheap set as there will be other places on the car where you can use them – Click here (opens in new window).

Once this Torx screw has been removed, the aerial base can be removed.

Step 6. Remove the antenna base.

Refitting of the aerial is a direct reversal of the above process.
